An improved total synthesis of [F-18]FHPG starting from 1,3-dibenzyloxy2-propanol and guanine has been developed. [F-18]FHPG was prepared by nucleophilic substitution of the appropriate precursor with [F-18]KF/ Kryptofix 2.2.2 followed by a quick deprotection reaction and purification with a simplified Silica Sep-Pak solid-phase extraction (SPE) method in 10-15% radiochemical yield, and 70 min synthesis time from end of bombardment (EOB).
